Both the ancient Hebrews and the Cannanites, Wes, came from Semitic Akkadia, in Mesopotamia, and worshiped the same gods, but as they expanded westward and separated, just as two groups of the same species, isolated from each other, will evolve into separate species, so the gods evolved, and the two groups fought continuously over whose god was greater, the exact same situation we have today with Yahweh and Allah - two separate religious "species" from the same origin.
